Abstract: 
Agricultural and urban waste consist of large quantities of biomass and petroleum originated waste. These two categories are rich in hydrocarbons which can be utilized again after their first life cycle. Pyrolysis is a thermochemical process in which solid hydrocarbons decompose in conditions of high temperatures and lack of oxygen (Ο2).Normally the chemical elements of carbon (C) and hydrogen (H2) react by releasing heat called combustion in an environment with oxygen. This paper examines the maintenance of high temperature conditions with oxygen deficiency that keep these chemical elements (C and H2) distinct until their formation of new chemical compounds of hydrocarbons. These new synthesis have a different number of C and H2 atoms from the initials, which form fuels in solid, liquid and gas state . It turns out that pyrolysis is the first stage in all the other thermochemicals, as well as combustion and gasification. Without pyrolysis, combustion and gasification cannot take place. This research presents analyzed parameters that affect the decomposition of hydrocarbons and the composition of new with characteristic suffixes. These new fuels can be utilized into conventional equipment that can produce heat, lighting, mechanical work and electricity.
